Just thinking about the suggestion you said about lifting one rafter at a time and removing sections might actually be the way to go.
So basically build a little something to hold the weight of the rafter, cut out that section or treat it, and then just replace a bit of the log? The sections I'm concerned about are not just a little bit rotted, I mean they are like 80% gone.. You can just dig a few places out completely with a screwdriver.
There is one section of log that is 6 meters (20') that is too bad to repair and several rafters are connected to that. Would you split this log into pieces and put them up individually for each rafter? I would imagine as long as each log section are pegged into the log below it should be structurally ok. Is that how it is typically done?

Are the sills resting on a chip board and is the rot attacking the sill up from the chip board? If you could post a pic of the rot it would be a good idea to understand the cause to come up with a corrective action. I see lots of sunlight so assuming you are seeing lots of moisture and wind driven rain in the addict?
